I use Adobe BrowserLab to test my sites in multiple browsers, recently I've discovered all my SilverStripe sites had stopped working in BrowserLab, I would only get this message:
This happens on sites that used to work fine in BrowserLab that haven't been touched, and even the SilverStripe demo site at demo.silverstripe.org.
So I posted on the BrowserLabs forum, and here is a reply from their developer:
"When I preview http://demo.silverstripe.org/ on my dev browser server errors are generated when decompressing the main page - java.io.UnsupportedEncodingException: "UTF-8". I checked another page that uses gzip compression and UTF-8 encoding and it works fine - http://shop.cascade.org/. This leads me to believe that there perhaps is a problem with the encoding on the pages this person is previewing."

So is this a SilverStripe bug?
